Abstract
An effective evacuation of buildings is critical to minimize casualties
due to natural or anthro-pogenic hazards. Building evacuation models
help in preparing for future events and shed light on possible
shortcomings of current evacuation designs. However, such models are
seldom compared or validated with real evacuations, which is a critical
step in assessing their predictive capacities. This research focuses on
the evacuation of a K-12 (kindergarten to 12th grade) school located
within the tsunami inundation zone of Iquique, Chile. An agent-based
evacuation model was developed to simulate the evacuation of
approximately 1500 children and staff from the school during a global
evacuation drill carried out for the entire city. The model simulates
the motions of heterogeneous human agents, and the simulations were
validated using video analysis of the real event. Resulting error
estimations between predicted versus measured flow rates and evacuation
times are 13.5\% and 5.9\%, respectively. The good agreement between the
simulated and measured values can be attributed to the known
distribution of students and staff at the start of the drill, and their
known exposure to emergency preparedness protocols. However, the results
presented herein show that this mathematical evacuation model can be
used for logistical changes in the emergency planning.
